To all whom it may concern "Be it kn'own that I, LOUIS N. D. 71L- LIAMS, a citizen of the United States, residing in ()gontz, Montgomery county Pennsylvania, have invented certain Improve; ments in Knitting-Machine Needles, of which the following is'a specification.

The object of m v' invention is .to provide an effective pivot construction for the swinging .needles employed in certain types of.

knitting machines, for instance in that type of machine shown in the U."S.'Letters Pat ent of Robert V. ScothNb; 834,763, dated October 30,1906. This object-I attain in the manner hereinafter set forth, reference beinghad to'the accompanying drawing, in

which- Figure 1 represents, disconnected from one another, the parts of a needle of the type to which my invention relatesjl ig. 2 represents the parts of the needleapplied to one another but not secured together: Fig. 3 shows the needle in its finished condition; FigQd is a transvers e section on the line a e, Fig. Fig.5 is a transverse-section construction of needle in accordance with my HIYQHUUXX. Figs. and are on a larger seaie than the remaining figures of the drawlng.

Heretofore needles such as those to which my invention relates have been provided with a segmental bend in the stem of the needle,to constitute a pivot member. but in stem on which the cams act to impart movement thereto. In carry ng out 1n v present invention, therefore, I have provided a pivot member whichcan be accurately adjusted on the stem of the needle and can then be secured to said stem berond risk of displace ment thereon; This may be accomplished by soldering the pivot member to the stem of the needle. butl prefer to dispense-with the use of solder or otln extraneous means for e'ttecting the desired connection.

In carrying outmy invention I use for the pivot member of the needle a block 1, preferably circular, this hloclr having in one ot its faces a transverse groove 2 of such. width that the stem 3 of the needle willfit" snugly therein, and of such depththat the side walls of the-groove Will-project to some extent above the faceof the needle stem wherrthe latter has been seated upon the base of the groove. By. means ot a suitable positioning gage the, block -1-is firstdisposed upon the stem of theneedle in its proper relation to the needle Land to the end.5 of the needle stem upon which act the-cams for.

imparting swingingmovement to the needle,

and the block is then securedto the stcml This may be-donebysoldering or brazing together the needle .stem. and block, ,but- I prefer to efiect' the" connection without the use of solder by applying pressure .to,the grooved face of the block upornone oi'fboth sides of the groove,tlpreterablv'upon both sides, so as to displace the metal-actedupon and cause a portlon of 1t to flow over the stem of the needle and therebv confine the 'latter so firmlyin the groove ofthefbl'ock'as to not only prevent it from. being forced out at the said Igroove but also to ipreventoany "longitudinal.movement of the block 1 upon the needle stem. In the needlegshown in the drawing pressure has been apphed-to'the face of the block at two separated points on each side ofthe groove, therebvdisplacing the metal at these points and causing sa d displaced metal to form fins 6,.which ove r lap the stem of theneedle, as shown'inFig. 5. In order to aid the displaced portions of the-metal in the performance eitheir intended function, the needle stem is preferahlv notched inthose portions where the.

fins 6 engage it, such notches being shown at,

Serial in. 582,697. it i 7 and said. notchesv being preferably, tapered or beveled-as shown in' Fig. 5,jwlierehy, when the displaced metal fiowsover the stem of the needle'the inclined bases ofrthe notches will act as wedges and the needle stem will be forced firmly into contact with the base of the groove 2.

ii'hile I always prefer, in carrying out my invention, to use the circular block 1, I may, in'som'e cases, adopt the construction shown in Fig. 6, in which the block l has formed upon it'a stem 3* for the actionof the cams whereby the swinging movements are imparted to the needle, the latter having a short stem 3 which is secured to the block 1- by displacement of part of the metal of pivot member consisting. of a circular block secured to the stem of the needle.

2. A knitting machine needle having a pivot member consisting of a circular block with transverse groove therein, the stem of the needle being secured in said groove.

3. A knitting machine needle having a pivot member consisting of a block with transverse groove which receives the stem of the needle, said stem being secured inthe groove by a displaced portion of the metal of the block. p

4:. A knitting machine needle having a pivot member consisting of a block with transverse groove which receives the stem of the needle, said stem being-secured in the groove by a displaced portion of the metal of the block on each side of the groove.

5. A knitting'machine needle having a pivotv member consisting of a block with transverse groove which receives the stem of the needle, said stem being secured in the groove by a displaced portion of the metal of the block, said displaced metal overlapping the stem of the needle.

6. A knitting machine needle having a pivot member consisting of a block with transverse groove which receives the stem ofthe needle, said stem being secured in the groove by a displaced portion of the metal of the block on each side of-the groove, said displaced portions of the metal of the block overlapping the stem of the needle on each side of the same.

7. A knitting machine needle having a notched stem, and a pivot member consisting of a block grooved to receive said stem and having portions of the metal of whichit is composed displaced so as to engage the notched portions of the stem.

-8.A knitting machine needle having a stem with notches at each side of the same, and a. pivot member consisting of a block having a groove for the reception of the needle stem, portions of the metal of which the block is composed being displaced so as to engage the notched portions of the stem.

9. A knitting machine needle having a stem with beveled notches therein, and a pivot member consisting of a block having a groove for the reception of the needle stem, displaced portions of the metal of the block engaging the notched portions of the stem, .and by pressure upon the inclined bases of the notches forcing said stem into contact with the base of the groove.

10. A knitting machine needle comprising a stem having the needle at one end and at .the other end a portion for being acted upon by the cams whereby swinging movement is imparted to the needle, said needle stem having, at an intermediate point, a pivot member consisting of a circular block to which the stem of the needle is secured.

11. A knitting machine needle comprising a stem having the needle at one end and at the other end a portion for being acted upon by the cams whereby, swinging movement is imparted to the needle, said needle stem having, at an intermediate point, a pivot member consisting of a, circular block with transverse groove therein, the stem of the needle being secured in said groove.

12. A knitting machine needle comprising 'a stem having the needle at one end and at the other end a portion for being acted upon by the cams whereby swinging movement is imparted to the needle, said needle stem having, at an intermediate point, a pivot member consisting of a block grooved to receive the needle stem, which is retained in position in such groove by means of a displaced portion or portions of the metal of which the block is composed.

13. A knitting machine needleliaving a stem with pivot member thereon comprising a block having a groove for the reception of the needle stem, and, on either side of said "groove, spaced fins overlapping and retaining said needle stem.

14. A knitting machine needle having a stem with pivot member thereon comprising a block having a groove for the reception of the needle stem, and, on each side of said groove, spaced fins overlapping and retaining said needle stem. I

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
